Water causes many electrolytes to dissociate __________.
lana66690 [7]

Answer:

2. because water molecules are dipoles and the dipoles orient in an energetically favorable manner to solvate the ions.

Explanation:

For the water to dissociate electrolytes, this one has to orientate its molecules in an energetically favorable way that allows them to interact with ions and dissociate electrolytes. This has to do with the way that intermolecular forces of a solute and a solvent, which is the water, interact to form a solution. The different intermolecular forces that interact in a solution are dipole-dipole force, ion-dipole interactions, Van Der Waals forces, and Hydrogen bonding.

What is the hybridization of the central atom of each of the following molecules? a.) H2O b.) PBr5 c.) COCl2? Thank you so much!
ira [324]
 <span>The notion of hybrid orbitals was "invented" by Linus Pauling in 1931 to explain the observed geometry of mostly organic molecules. Today, we find that hybrid orbitals are pretty much confined to the central atoms found in the second period of the periodic table. Periods 3 and up .... not so much. 

(a) H2O ..... O is the central atom, tetrahedral, sp3 hybridization 
(b) PBr5 .... P is the central atom, maybe sp2 for the three equatorial bonds * 
(c) COCl2.. C is the central atom, trigonal planar, sp2 hybridization </span>

Gallium is a metallic element in Group III. It has similar properties to aluminium.
Liula [17]

Answer:

Gallium has Orthorhombic and forms ionic bonds with metals

Explanation:

The structure of gallium is Orthorhombic and it has a high neutron capture cross section. It is very stable in dry air but oxidizes in moist air. It reacts with oxygen to form Ga2O3. It has a valence of III. Its electronic configuration is  

Ar 3d10 4s2 4p1

It is found in the 3A group of periodic table and it mostly forms ionic bonds with metal.
